Leptolalax bourreti (Bourret's Asian toad or Bourret litter frog) is a frog species in the family Megophryidae.

It is known with certainty only from the vicinity of its type locality in Sa Pa in northern Vietnam.

Earlier records from Laos refer to Leptolalax eos (described in 2011) and those from Thailand probably to an unnamed species.

[1] Leptolalax bourreti is a large-sized Leptolalax: males measure 28–36 mm (1.1–1.4 in) and females 42–45 mm (1.7–1.8 in) in snout-vent length.

The colouration of irises is variable, clearer above, and coppery, green, or brownish.
